When Do You Have to Charge Yourself VAT? A Complete Guide 

Normally, suppliers account to HMRC for VAT due on their supplies. However, in certain situations, this position reverses and customers must account for VAT themselves. These reverse charge and self-supply mechanisms are designed to prevent VAT avoidance, create level playing fields, and combat fraud. 

1. Purchasing Services from Abroad 

Services obtained from overseas suppliers come VAT-free, but UK businesses must apply the ‘reverse charge’ procedure. This ensures UK businesses aren’t disadvantaged compared to purchasing domestically. 

How it works:

• Account for output tax on the full supply value (Box 1)
• Claim input tax (subject to partial exemption and business use rules) (Box 4)
• Include the supply value in both Boxes 6 and 7 

The consideration paid to the overseas supplier excludes UK VAT but includes any foreign taxes.

Timing follows the earlier of payment date or last day of the VAT period when services are performed, with UK VAT rates applied as if the service were supplied domestically. 

Common examples include:

• Professional services (legal, accounting, consultancy)
• Digital services and software licences
• Marketing and advertising services
• Intellectual property licensing 

2. Construction Industry Domestic Reverse Charge 

Since 1 March 2021, specified construction services between VAT-registered businesses use domestic reverse charge to combat fraud in the construction sector. 

Services covered:

• Building and construction work
• Demolition and dismantling services
• Repair, maintenance, and cleaning of buildings
• Installation of fixtures and fittings
• Painting and decorating
• Hire of construction equipment with operator 

The system applies only to supplies between VAT-registered businesses.

Suppliers issue invoices showing 0% VAT with “Domestic reverse charge” notation, whilst customers account for VAT at standard rate (20%).

Both parties must maintain detailed records. 

Key exceptions:

• Supplies to non-VAT registered customers (normal VAT applies)
• End-user supplies (e.g., to homeowners)
• Certain professional services when not providing construction services 

3. Mobile Phones and Computer Chips 

To combat Missing Trader Intra-Community (MTIC) fraud, specific goods face reverse charge requirements when supplied between VAT-registered businesses with individual values of £5,000 or more. 

Process requirements:

• Supplier provides invoice showing goods description and “reverse charge” notation
• No VAT shown on supplier’s invoice
• Purchaser accounts for output tax and may claim input tax 

4. International Goods Purchases 

Post-Brexit arrangements have changed how VAT applies to international goods purchases, creating different obligations depending on the origin country. 

From EU countries:

• Import VAT applies at point of entry
• Postponed VAT accounting available for VAT-registered businesses
• Monthly declarations required for significant importers 

From non-EU countries:

• Standard import procedures with customs duties potentially due
• Import VAT charged at UK rates
• Freight forwarders often handle declarations 

5. Deregistration Self-Supply 

When leaving VAT registration, businesses face deemed supplies on remaining stock worth over £1,000 total, but only on goods where input tax was previously claimed.

Output tax becomes due at current VAT rates based on cost or market value (whichever is lower), with no input tax recovery available. 

Planning considerations:

• Time deregistration to minimise stock levels
• Consider disposing of high-value stock beforehand
• Maintain accurate stock valuations 

6. Flat Rate Scheme Exit 

Businesses leaving the Flat Rate Scheme whilst remaining VAT-registered face capital goods adjustments on items where input tax was claimed before joining FRS.

This creates self-supply charges on current market values affecting computers, machinery, vehicles, and equipment, with no input tax recovery available. 

7. Fuel and Power for Private Use 

When business fuel is used privately, self-supply charges apply based on HMRC’s published fuel scale charges, applied per vehicle per quarter.

Alternatively, businesses can maintain detailed mileage records for actual business use percentage calculations. 

8. Land and Property Transactions 

Complex self-supply rules apply in property scenarios, particularly around option to tax elections and transfer of going concern provisions. 

Option to tax considerations:

• Self-supply when opting to tax previously exempt property
• Based on market value at time of election
• Affects future rental income VAT treatment 

Transfer of going concern rules prevent VAT charges on business transfers, but strict conditions must be met, and professional advice is essential. 

9. Motor Trade Specific Rules 

The motor trade faces unique self-supply situations, particularly around margin schemes for second-hand car dealers and demonstrator vehicle sales. 

Key scenarios:

• Cars moved from margin to standard scheme
• Business cars sold to third parties
• Complex valuation rules based on purchase price or market value 

10. Digital Services and E-commerce 

Modern business models create new reverse charge scenarios affecting online marketplace facilitators, digital platform operators, and Software-as-a-Service providers. Emerging rules for cryptocurrency and digital asset transactions require professional advice for complex arrangements. 

Common Compliance Issues 

Businesses frequently encounter problems with record keeping, timing errors, and valuation mistakes. Detailed records of all reverse charge transactions must be maintained with separate identification in VAT accounts and supporting documentation for overseas suppliers. 

Typical errors include:

• Incorrect time of supply calculations
• Delayed recognition of reverse charge obligations
• Currency conversion mistakes
• Omitting foreign taxes from valuations
• Incorrect market value assessments for self-supplies 

Penalties and Interest 

Even when reverse charge results in VAT-neutral positions, HMRC can assess penalties and interest for non-compliance.

Common penalties arise from failure to account for reverse charge VAT, incorrect return entries, late recognition of obligations, and inadequate record keeping. 

Mitigation options:

• Voluntary disclosure of errors
• Reasonable excuse arguments
• Professional representation in disputes 

Best Practice Recommendations 

Regular monthly reviews should assess international purchases, construction industry transactions, and digital service acquisitions. Staff training ensures accounts teams understand reverse charge rules with regular legislative updates and clear procedures for different scenarios. 

System requirements:

• Accounting software configured for reverse charges
• Automated alerts for threshold breaches
• Regular reconciliation procedures 

Professional advice becomes valuable for complex transactions, with annual VAT health checks recommended and proactive planning for business changes. 

Conclusion 

Reverse charge and self-supply rules affect most VAT-registered businesses in various ways. The complexity and penalty risks make professional advice valuable, particularly for businesses with international transactions, construction activities, or complex corporate structures.

Regular reviews and proactive compliance management prevent costly errors whilst ensuring businesses benefit from available input tax recovery and meet all HMRC obligations.
